Specification of Letters Patent.

Patented Sept. 22,- 1291141.

Application filed February 7, 1912. Serial No. 676,090.

Be it known that I, HENRY WEBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Work-Guides, of which the following is a specification.

This invention relates to improvements in work guides of the type shown and described in my application Serial No. 541,212, and which guide is particularly adapted though not necessarily limited in its use in connection with stitching or stapling machines of the type shown and described in my application Serial No. 541,209, for diroofing and insuring the proper positioning of the work with respect to the stitching or stapling mechanism, and to which applications reference may be had for a full understanding of the parts not specifically described herein.

One of the objects of the present invention is to provide an improved device of this class which may be readily attached to the machine and adjusted and held in various positions corresponding to the adjustment of the work support and the stitching mechanism.

A further object is to provide an improved device of this class which will be of sufficient rigid construction to prevent vibration thereof, but which will yield sufficiently under the action-0f t e stitching or stapling mechanism.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention, and in which Figure 1 is a front elevation of a portion of the stitching or stapling mechanism having an improved attachment constructed in accordance with the principles of this invention applied thereto, showing in full lines the attachment in one position and in dotted lines in another position. Fig. 2 is a right hand side elevation of the parts shown in Fig. 1. Fig. 3 is a top plan view as taken on line 3, 3, Fig. 1. Fig. 4 is a detail cross-sectional view of a portion of the work guide, showing the manner in which the flaps of the work are overlapped.

of the work guide, away. Fig. 6 is a top Fig. 7 is a top plan view of the parts shown in Fig. 5, with parts broken away. Fig. 8 is a side elevation of the guide proper, with parts removed.

Referring more particularly to the drawings and in the present exemplification of the invention, the numeral 10 designates generally a main support, to which is secured a work-supporting arm or member 11. This arm or member 11 is adapted to be adjusted laterally with respect to the support 10 inany suitable manner such as by means of an adjusting device 12, whereby the work-supporting arm may be positioned with respect to the stapling mechanism designated generally by the reference numeral 13 in Figs. 1 and 2.

All of the above mentioned parts may be of any desired construction and form no part of the present invention, but constitute the subject-matter of a separate application.

The work-supporting arm 11 in the present form of the invention has secured thereto table sections 14:, the tops of which are substantially flush with the top of the arm 11, and the sections are provided with a plurality of bolt apertures 15, which are preferably formed in metallic strips 16 countersunk in the face of the table section so that their upper faces will stand substantially flush with the top of the table sections. v ranged parallel with the arm 11 and on each side thereof. Similar strips 17 18 may be provided and countersunk in the face of the table sections and so arranged to extend across the table sections and transversely with respect to the strips 16. A gage 19 is provided with rearwardly projecting armspr portions 20, which latter are provided with slots through which fastening devices 21 pass so as to engage the bolt apertures 1n the strips 16. This gage 19 extends transversely with respect to the arm 11, and may be adjusted longitudinally with respect to the arm by loosening the fastening devlces 21. After'adjustment, the gage may besecured in its desired position by tightening the fastening devices.

The work guide comprises spaced members 22, 23 arranged one above the other and These strips 16 are preferably ar-' connected along one edge by an upright or web 24. The member 22 projects for some distance beyond the extremities of the member 23 and constitutes a work-supporting bar, the forward extremity 25 of which is preferably reduced laterally as shown in Fig. 7, and a clencher block 26 is carried by this portion 25. The other extremity of the bar 22 is enlarged laterally, as shown, to project beyond the outer face of the web 24, and the portion of the web 24 adjacent this enlarged portion of the bar 22 is deflected as'at 27 to form an inclined guide for directing the Work between the members 22, 23.

In machines of the type illustrated in the drawings the head 29 which carries the stapling and stitching mechanism 13 is swiveled for movement in the outer terminal 29* of the goose-neck or support 29, said outer terminal 29 of said goose-neck being stationary. Though the head 29% may have any number of adjustments, in the present exemplification of the machine, it is arranged to swing to three .a ajusted positions in order that the staple may be driven through the work at three different angles, dependent upon the class of work being operated upon.

The work guide heretofore described is supported by and attached to the outer terminal 29 of the goose-neck 29 and therefore is stationary with respect to the movement of the head 29*. As set forth more clearly in Fig. 2, the guide bar 22 is arranged transversely with respect to the arm or bar 11 and is always parallel to the gage 19, irrespective of the position of the bar 11 and the head 29.. The lateral edge of this work supporting bar 22 adjacent to the gage 19 is beveled or inclined as at 28 in order that the work may be easily directed into the guide.

In order to mount the work guide heretofore described upon the outer terminal 29 of the goose-neck, a horizontal work plate is secured to one side of the outer terminal 29 by vertical bars attached to the inner end of the bracket plate 30, and secured to the outer terminal 29 by suitable attaching means 31, the upper terminals of said bars. being connected at a point adjacent the outer end of the bracket plate by a plurality of obliquely arranged braces. The guide is adjustably secured to the bracket plate 30 in such a manner that the guide is provided with three adjustments with respect to the bracket late 30 in order that the same may be adusted to conform with the various adjustments of the head 29, and at all times rest parallel to the gage 19 and project laterally and horizontally from the outer terminal 29 of the goose-neck 29 in a direction similar to that of the bracket plate 30. This bracket plate 30 is provided with a series of apertures or openings 32, 33 and 34 arranged a in pairs and spaced from each other longiwith the Work guide through the medium of the pin 36 passing through a pairof uprights 37 mounted or formed upon the plate or web 23,.sa-id horizontal portion of the bracket 35 being retained between said uprights 37. In order to provide a limited pivotal movement about the pin 36, a slot 39 is formed in the terminal of the horizontal portion of the bracket 35 which engages a pin 38 arranged between the uprights 37, thus permitting the uprights 37 and the guide carried thereby to have a slight pivotal movement.

The horizontal head 35 of the bracket 35 is pierced by a plurality of fastening devices such as bolts 40 which are adapted to pass through any pair ofthe series of apertures 32, 33 or 34 formed in the bracket plate 30 and thus adjustably secure'the intermediate bracket 35 to the bracket plate 30. Dowel pins 41, diagonally opposed upon the bracket head 35 are provided to enter the openings 42 piercing the bracket plate 30 adjacent to the series of apertures 32, 33, 34 to insure the proper positioning of the intermediate bracket 35, andthe guide carried thereby. The corner of the plate 23 on the side of the member opposite to that upon which the member 24 is located and at the entrance end of the work guide is deflected or bent upwardly as at 43 to insure the positive entrance of the work into the guide.

From the foregoing description it will readily beunderstood that as the head 29 is swung in one of its three adjusted positions the stapling mechanism 13 carried thereby therefore will change its position relative to the bar 11. Inasmuch as the stapling mechanism 13 must constantly be vertically alined with one of the anvils or clencher blocks carried by the bar 11, it is necessary to adjust the bar 11 through the instrumentality of the screw 12. Thislmovement of the bar mimic It will be noticed that the openings 32, 33

and 34 are obliquely arranged in the bracket plate 30 and that there are as many pairs of openings as there are adjustments to. the head 29. so spaced from each other that the successive positioning of the intermediate bracket 35- pair of openings will aline a,

to each clencher block on the bar 11 with the clencher block or anvil 26 ment of the head 29 and the bar 11.

The work is fed into the guide in the manner shown in Fig. 4 and in dotted lines in Fig. 2, so that one edge of one flap will engage the web 24 and this will force the folded edge of the work against the gage 19. The work is also arranged with respect to the guide so that the upper plate or member 23 will pass between two of the flaps. When the overlapping flaps are advanced with respect to the work guide, they will pass over the clencher block 26 while other portions of the work will pass between the work guide and the arm 11. When the stapling mechanism is operated, a staple will be inserted throu h the overlapping flaps and will be clenched by striking the clencher block 26. In order to accommodate the work guide for the movement of the staple driving mechanism, the work guide is pivotally supported as above described so that the guide will yield slightly to permit the staple to be clenched by forcing the extremity of the work-supporting bar 22 downwardly toward the arm 11, the work guide thereby yielding to the operation of the stapling mechanism. With this construction, t will be manifest that all vibration of the work guide will be dispensed with. If desired, another gage 45 similar to the gage 19 may side of the work guide for directing and properly positioning another section of the work with respect to the stapling mechanism when two separate sections are secured together by overlapping portions of the edges of the sections and fastening them together by the stapling mechanism.
